PENCiL.

SPECIFICATION forming part of Letters Patent No. 317,838, dated May 12,1885.

Application filed November 13, 1884.

To all whom t may concern:

Be it known that I, OscAR MUssINAN, J r., a citizen of the UnitedStates, residing at New York, in the county and State of New York, haveinvented new and useful Improvements in Pencils, of Vwhich the followingis a specification.

ll/Iy invention relates to improvements in lead-pencils; and it consistsin the combination, with a case or handle and a lead-receiver, of asplit lead-clamp secured to the lead-receiver and provided with a cone,a conical sleeve, which slides on said split clamp and is'arranged tooperate upon the cone, and a disk or stop secured to the case.

On the accompanying drawings, Figure lis Y a longitudinal section of mypencil, showing` the position of parts to effect the clamping of thelead. Fig. 2 is a longitudinal section of the same showing the pencilready for use. Fig. 3 is a longitudinal section showing the leadunclamped. Fig. 4 shows a modification of part of the pencil. p

Similar letters indicate corresponding` parts.

In the drawings the letter A designates the tubular case or handle,which is made of any convenient length or size. On its lower end thecase A tapers, forming part of a cone, a, said cone being provided withan inner bead, c. f

Onto the upper end of the case A is snugly fitted a lead-receiver, B,which has drilled into it a longitudinal hole for the reception of theextension of the split lead-clamp C and the lead E contained therein.rIlhe lead-clamp C is securely glued to the lead-receiver B; or it maybe fastened in any other suitable manner.

Near the lower end of the lead-clamp C is formed -a cone, d, the slotgin said lead-clamp extending also through the cone d.

c is a conical sleeve, which slides on the lead-clamp C, and is of sucha size that when it is forced upon the cone d the split clamp C issufficiently tightened upon the lead E contained therein to hold saidlead E lirrnly in position.

` F is a disk or stop fitted in the case A, and is secured therein inposition by a screw, f, or, by preference, it may be secured, as shownin Fig. 4, by means of two inner beads, f f, formed in the tubular caseA, the latter method of fastening being stronger, and also (No model.)

serving to improve the appearance of the pencil.

rlhe lead-receiver B, before mentioned, is fitted in the case A so thatit requires some little force to push the same backward and forward inthe ease A, in order to prevent slipping ofthe lead-receiver when thepencil is in use. If, now, the lead-receiver B, from the position shownin Fig. 3, be drawn backward in the case A the cone d is brought intocontact with the sleeve c, and causes said sleeve c to be carried alonguntil it is brought to a stop by the disk F. On further drawing backwardthe lead-receiver B, the cone d is forced into the sleeve c, and thelead-clamp C is forced upon the lead, Fig.` l. If the lead-receiver B isnow pushed forward until the pencil projects beyond the lower part ofthe case A, or until the sleeve c strikes lightly against the bead a' outhe inner surface of the conical part c of the case, as shown in Fig. 2,the pencil is ready for use.

In order to return the lead from the leadclamp C and allow the same toslide in the lead-receiver B, the lead receiver is pressed forward tosuch a position that the sleeve c impinges against the bead c on theconical part a of the case A, and is forced back from the cone d. whichallows the lead-clamp `C to expand, Fig. 3.

As will be seen from the above description and the drawings,theconstruction and mechanism of'niy improved pencil are extremelysimple, but at the same time very efficient and durable, and it allowsof adjusting the lead very easily and quickly.

VhatIclaim-as new, and desire to secure by Letters Patent, is-

The combination, substantially as hereinbe ICO
